Former Genoa striker Carlos Alberto 'Pato' Aguilera is reportedly recovering in intensive care in Montevideo after heart surgery.
Reports in Uruguay indicate that the former Rossoblu forward, who turned 47 last week, was admitted to hospital on Sunday with coronary artery disease.
He is understood to have undergone a double surgery procedure and is now recovering in intensive care.
The Uruguayan international, capped 65 times by his country and with 23 goals to his name, enjoyed a successful three-year stint in Italy with Genoa, where in 96 games he netted 33 goals.
Statistically one of the club's most prolific marksmen in their history, Aguilera also played a significant part in the team's run to the UEFA Cup semi-finals in 1991-92, where they lost to eventual winners Ajax.
In that run, two of Aguilera eight competition goals came in a 2-1 win at Anfield that saw Genoa become the first Italian team to beat Liverpool at their own ground in European competition.
The forward was convicted in 1996 of drug dealing and pimping in the peninsula, but left the country before he was sentenced. He was allowed to return to Italy after being granted a pardon by the Italian government in 2007.
